WARNING: Backup IMEI before you flash or factory reset. ROMS and Radio's

WARNING: Because all these MTK6516 phones look similar in specs, it may be tempting to flash ROM's from one to another. Be careful! If the ROM you are flashing is for a model with different screen driver, or a different camera driver, best case is those devices will not work, and worst case you end up with a brick.
So we will list ROMS only for specific phones below.
The Radio portion of the ROMS may or may not be the same throughout all MTK6516 phones, even not being dependent on OS. More info is needed, please provide feedback, especially if you have a newer radio.
